[Scarless surgery: a vision becoming reality?].

As minimal invasive abdominal surgery became established in the last decades, further minimization of the surgical access is in the focus now. Although laparoscopic instruments and camera systems become diminished in size there is still a need for a minilaparotomy for extraction and anastomosis of organs. NOTES (Natural orifice transluminal endoscopic surgery) aims to avoid this minilaparotomy. Consequently, laparoscopic-assisted procedures become pure laparoscopic surgery. The transvaginal access is the most common performed NOTES procedure. The acceptance in women is high. The feasibility of NOTES cholecystectomy is scientifically proofed. The procedure is associated with less pain than the common four-port laparoscopic surgery and does not interfere with the sexual well-being. There are no access-related infections; the abdominal wound infection and incisional hernia rate are low. In left sided colonic resection the transrectal access makes NOTES available for both genders.
